Can't submit form within "onbeforeunload" event using Edge

Question

Hi,

We have javascript code to submit html form inside "onbeforeunload" event using IE and it has been working fine for years. But the same code is not working after switching to Edge browser and the problem is the form submit. Do you have any suggestion how to make html form submit working in "onbeforeunload" using Edge?

We need this function because we want to save page page after users click red 'X' button on the top right corner.

Thanks.

Hi @Ligong Zhu ,

According to your description, I created a simple demo and reproduced this issue your mentioned. And I found this problem in both Chrome and Edge. But it does work very well in IE. According to this situation, I recommend you to use Edge IE mode.

Just simple settings: settings and more ( ... ) -> Settings -> Default browser -> turn on the option Allow sites to be reloaded in Internet Explorer mode to Allow. And then you could reload the page in IE mode. And use it like this:

In addition, for this issue, you could also send feedback to the relevant team via this link.

Hope this can help you.

Thank you very much for the quick response In that case, is it possible to disable or hide red X button from Edge so that users can't use it, or is there another event we can use to submit current form when users click on this red X?
